To all whom z't may concern.'

Be it known that I, FRANK H. MEINERS,

State of Chio, have invented certain new and uset'ul improvements in Flushing-Valves, of which the following is a specification.`

' My invention relates to flushing valves, especially for water-closet tanks. Its object is to simplify devices ofthis character, and

. to renderthem more reliable and less liable to dera'ngement and leakage.

My invention consists in the combination of parts and in' the details of construction and arrangement of parts, as will herein be more fully described and claimed.

In the drawing: Figure 1 is a. through one end part of a tank and a device embodying my invention, mounted therein, parts being shown in flushing position by dotted lines;

Fig. 2 is a sectional plan view, the section being onv a plane corresponding to the line 2 2 of Fig. 1;

Fig. 3 is an inverted sectional plan view, the section being-on a plane corresponding to the line 3 3 of Fig. 1;

Fig. 4 is an enlarged vertical section of the valve-seat ring.

Where used in a tank, as indoors, and as shown in Figs. 1, 2 and 3, there is a valvebody 1 within side chamber 2 Ainto which runs an overflow pipe 3, the height o1c which pipe 3 determines the maximum height A of water in the tank 4. This bodv 1 has a-neck 5 extending through the bottom 6" ofthe tank 4, with a. flange 7 having a gasket 8 between itiand the bottom'; and there is a nut 9 screwed on the neck with a gasket 1 0 between it and said bottom. The usual flushing pipe 11 connects with the lower end of the neck 5, to lead to the closet bowlfnot shown.

The top of the body 1, above the side chamber 2, has its interior diameter less than' that of the neck 5; and comprises a lower continuous interiorly threaded part '12 and analpper part with lateral openings 13.. Into the threaded part 12 is screwed an exteriorly threaded ring 14 with its upper interior 'increasing in diameterupwardly with a. strai h t taper, as best seen in Fig. 4. Its lower edge has notches 15, in which a Spanner may be engaged to screw the'rmg into the threaded part 12 of the body 1.

Specification of Letters Patent.

vertical lsectional view The upper part of the ring forms the annular seat for the valve member, which is in the form of a downwardly tapered valve-plug 16; the taper of the plug being such the.plug wedges securely in its seat This plug is sere-wed onto the lower end of a stem 17, and the top ot' the body 1 has a tubular continuation with interior diameterA uniform with that of the upper interior of Patented Mar. 13,1917.

the body; this continuation being preferably in the form of a thin tube 18 screwed into the valve-body top,as shown. Onto the top of the continuation or tube 1S is screwed a cap 19, with a central-hub 20 having a central opening through which extends thc stem 17 to be guided thereby. The upper perimeter of the plugis. only very slightly less in diameter-than is the interior of the body 1 andtube 18. Thus, the valveplug' and stemmay slide up anddown in the body 1 and tube 18, and the plug will be accurately guided into its seat.

The upper end of the stem 17 has an eye 21, and alever 22 has a fork 23 receiving the eye 21, between its members, with a pi'n 24 through its members and the eye. The lever 22 has a fulcrum 25 on the upper edge of the tank 4; and its other end, outside the tank, has, as hereV shown, a chain 26 connected to it. with a. handle 27 on the lower end of the chain. The parts are so proportioned that the valve-plug 16 against the rethe chain 26 and handle 27 may have substituted for them any other well known devices. For instance, with a.lowdown tan-k, any ot the various kinds of handles orlevers used on flow-down tanks, ,maybe useddepending upon circumstances. But in any instance, the valve-plug and attached parts must slightly overcome the opposition of these other parts.

Thus constructed, when the chain 26 or its equivalent is pulled down, the valve-plug 16 is raised through the tubular guideway to'a' position' about as indicated by the dotted lines in Fig. 1. This allows the water to'rush out through the openings 13, past the valve-seat, and down through the fiushing pipe 11 to the bowl. nearly balanced condition vof the valve-plug 16, it does not descend quickly when the chain 26 is released; but slow enough to Owing to the I allow an ample flushing period before the A ing the flushing plug wedges in its seat, thus cutting otf the flow until it is raised again.

It will be seen that the parts are vfew, and have a very simple relation to each other, and all but the gaskets 8 and l0 may be of metal, eliminating the use of rubber or other soft material in the valve itself. As the valve-seat wears, the plug 16 sinks lower into the ring 14; and when this ring is worn through enough to impair the efficiency. of the seat, a new ring 14 may be substituted for it. This is done by disconnectpipe 11, reaching the ring M from the bottom exterior of the tank, without the necessity of disturbing the parts inside the tank.

I claim: f

In combination, a hollow body with an interior valve aperture and an upwardly facing annular valve-seat around said aperture and withupper and lower openings respectivehv eitirely above and entirely below said valve-seat, a hollow extension on said bodyy extending upward from above said upper opening, an inclosure outside said body and extension, communicating with and adapted to confine water in communication with said upper opening, a, downwardly tapered valve-plug sliding down in said extension past said upper opening and wedging down in said valveseat entirely below said upper opening, or sliding up in said extension far enoug past said upper opening to have its fall retarded by water below itin said extension, and withdrawn entirely from said valve aperture, and means connected to said valveplug to oppose the downward sliding of said valveplug, in such degree that 1t is only slightly overcome by said valve-plug falling against the resistance of the water in said extension when said valvelug is raised past said upper opening as a oresaid and there is a continuous body of water communicating through both of said openings and the valve aperture.
